ComfyUI - Getting Started : Episode 2 - Custom Nodes Everyone Should Have

In this tutorial we cover how to install the Manager custom node for ComfyUI to improve our stable diffusion process for creating AI Art. I also cover the nesting of nodes, installing the efficient nodes, and a few other little nuances that will set you up for success as you use this amazing tool

2:18 its "git clone" not "pull" you can use "pull" command to update the files later. If you not gonna use "clone" you will just get an error `fatal: refusing to merge unrelated histories` like in the video.

Amazing Tutorials! Very clear, very methodical and without fluff. Please keep them coming. If you don't mind, I want to ask if there is a inpainting workflow with low denoising values? The one in the documentation is replacing 100% of the masked content, but I want to only do a bit of denoising with 0.25 like in A1111. And not replace everything under the mask. ComfyUI is using a generic gray background for the masked content because it's deriving it from the alpha channel AFAIK. And the gray is showing through at low values.

[@RobertWatts1957]

Are you sure about this "git pull" command for a first time install? It failed for me, but "git clone" worked.

[@jitgo]

Agree, for a first install of this manager, 'git clone' works, 'git pull' does not (for me anyway)

[@DrSnakeGamez]

Indeed, Git pull will only work for subsequent requests, like updating a repository. For initial install u would, like u already mentioned, need to run git clone first

[@sedetweiler]

Sorry, you are correct. "git clone" is needed for the first time! Sorry about that!

[@sanderlenten10]

[@generichuman_]

This is giving me some ideas. I want to dig into the python development to make some nodes that integrate with GPT4. A user could provide an openai key and utilize GPT 4 for automating the generation of prompts. Example "Give me a list of 20 descriptive prompts that include artists that have a dark and eerie feel", or whatever.

[@sedetweiler]

Someone beat you to it! 😉 Check over at civit as there are a few options.

Does ComfyUI have a randomized variable &/r math node? Imagine I want to have 2 different prompts feed but I want the space/strength they take up total 100% but randomize the proportion. I'd want to randomize 1-100 then find the difference from 100 & feed value X to prompt 1's proportion & value Z (remainder) to prompt 2's. Or other ways to feed values randomly &/r with math?

The first part at 46 sec --> I have opened the .yaml file and replaced the base_path: like this: base_path: /content/drive/MyDrive/AI/models/ When I load the ui it does not load my models though.... (I restarted the notebook and Ui several times) Thanks in advance for any help.

[@sedetweiler]

Because it is running in a notebook, I believe you would need to make those models local to it by uploading the assets. I am not sure on this, but it needs those models.

@@sedetweiler hi, thanks for getting back! There must be a way somewhere in the notebook but it is so different from the deforum notebook I use and cant figure it out here… i edited the .yaml file and re-uploaded but still nothing.

what is with ComfyUI & "batch" presentation? I have a RTX3060 & using A1111 I can do a batch size of 4 at 768x768 so to get 16 done I change the batch count to 4. I can't ask A1111 to do 16 in batch size, directly. But when I do a batch count of anything more than 1 the 1st set of responses disappears, making it so I only effectively see the last batch. How can I get all the batch sizes X batch count to show in ComfyUI's image results? Am I doing something wrong?

[@sedetweiler]

You should set that in the empty latent, as that is really what the batch size is. Let me know if that works for you.

[@royjones5790]

@@sedetweiler In this case the Empty Latent's batch size takes up VRAM but the batch count purges memory between (at least that's how i understand it). So if my VRAM can only handle 1 1280x1080 if I switch Batch Size to 2, it'll crash. But if I change Batch Count to 2 it'll finish the first then go back again for the 2nd. In fact, I could feasibly make the Batch Count INFINITE if it's a clean purge. That's how I understand it to work
